Wife is a nurse. We did travel nursing for a while, first for 9 months out of 12, then 8, then 6. So those three years she was off 3, then 4, then 6 months. She loved being off for the holidays (though year #1, she flew home the day of Thanksgiving, so not sure if that can be counted).

If you're a nurse with 2-3 years recent experience, you can start applying now. I do recommend doing your research first, so you can reduce the number of rookie mistakes made.
